hi , I'm in the process of building a 55 foot pontoon boat,
any diy people have any ideas to make a deck, without the use of plywood, my first attempt was on a piece of flat galvanized ribbed metal, I fill the voids with wood chips and resin, what the following layer of a mat and roving, it's too flexible , I'm looking for the most reasonable price solution.
if I use a marine grade plywood as a core, gel coat all sides, two layers on each side, would anybody know the life expectancy of that?
